Abstract
Patente de Invenção: <B>"MéTODO DE PRODUçãO DE UM METAL REDUZIDO, E DE FORNO DE FUNDIçãO MóVEL PARA A PRODUçãO DO MESMO"<D>. A produção de metal reduzido pelo carregamento e empilhamento de uma matéria prima contendo um material contendo metal e um material de redução sólido em uma fornalha horizontalmente móvel de um forno de fundição móvel, pela disposição de uma camada de material de redução sólida na fornalha, pela formação de porções cóncavas na superfície de material de redução sólida, pelo empilhamento da matéria prima na superfície da camada de material de redução sólida, pela redução da matéria prima por aquecimento e fusão pelo menos uma vez do material na fornalha de modo a separar o metal e a ganga e os ingredientes de cinza, e pela descarga do metal da fornalha.
